'd have invented certain new and useful Inivproyements in. AerialTramways, of which the `following is speciiication.

This invention has relation to aerial tramways; and it consists in thenovel const-ruction and arrangement of its parts, as hereinafter shownand described. V

The object of the invention is to provide a tramway of the nature asstated which is especially adapted to be used for mining pur-` poses andfor transportation ,to and from mines.

. The invention consists primarilyT of an elevated track Orr-ail ofspecial formation, which is supported upon vertically disposed I- beams.The said beams are provided with socketed upper ends, the sockets ofwhich are adapted to receive the depending body of the The side flangesof the sockets project into spacesforined between the body of the railand the webs or flanges formed therewith, the outer faces of the flangesof said sockets being formed with seats to receive said webs andconforming thereto. In this manner the rail is effectively braced andsupported. The uper ends of the beams are irst slit and then expanded toforni the sockets. Suitable insulation is interposed' between the railand its supports, as the rail is used. as a ground-return for the.current employed for the puro'f propelling-'the motors or cars that Atthe joints of the rails side iish-plates are employed. Said lishplatesare provided with longitudinally-extending grooves, which receiveelectric bonds and house the same. The ends oi the said bonds are incontact with the ends of the adjacent rails, said connection beingeffected in the usual manner. The lower ends of the --beams are embeddedinthe ground, and

suitable braces extending in the line of the track are provided at thelower ends of the said beams.

From the following description other objects and advantages will appearas the tea-z tures of the invention are revealed.

In the accompanying drawings, Figurel is i a scenic view of the tramway'associated withA a mine. Fig. 2 is a transverse sectional viewyfish-plates attached thereto.

in the ground.

of the tramway, showing a motor in elevation thereon. Fig. 3 is a topplan view of a section of the tramway, showing the motor thereon. Fig. 4is a side elevation of one of the track-supports with parts broken away.Fig. 5 is a side elevation of the meeting ends of the track-railswith'parts' broken away. Fig. 6 is a transverse section of a rail withthe 7 is a side elevation of the inner face ofa fish-plate. Fig. 8 is ahorizontal sectional View of the I-beam,

-and Fig. 9 is a side elevation oi an intermediate portion of an I-beam.

The track-supports consist of the I-beams l l'1, which are embedded attheir lower ends At suitable intervals the said I-beams are providedwith the braces 2, which are bolted or otherwise secured at their upperends to the side flanges of the. beam and extend downward in the line ofdirection of the track and are embedded at their lower ends in theground. The incision or slit 3 is formed at the upper ends of the saidbeams, and the said upper ends of the beams are expanded or spreadlaterally, as at 4.

The track-rails 5 are provided with the top flat surfaces 6 and thesidev inclined webs or tlanges 7 7. The central body 9 extends down fromthe head ol' the rail 5 and at its upper yportion is spaced from theinner faces oi" webs 7. The extremities of the split portion of eachbeam l are shaped to it between the iianges 7 and body 9 and form seatsfor the lower edges and inner faces ofsaid webs.

The arm 10 is suit ably secured at an intermediate point in`laterally-disposed perforations bored in the ilanges of the I-beams 1.The electricwires l1 11 are supported by the outer ends ofv the said arm10. The said wires extend parallel to the track of the tramway. A

A t the ends of the track-rails 5 5 the electric bonds 12 are located.The said bonds have their ends secured in perf-orati'ons pro-- arebolted. The said plates are located under the heads of the Arails and inthe spaces between the body 9 and the side webs 7.. .The bolts 14 14pass through registering perforations in the body 9 and the flanges ofthe I-be'arn 1 and secure the rails 5 to .the'upper ends of the saidsupports. The insulation 15 is interposed between the under surface ofthe rail 5 and the upper end of the support `1 and also around the bolts14.

The motor or carrier consists of the traction-Wheels 16, which run uponthe rail 5 and are provided with the side flanges 17, which bear againstthe outer surfaces of webs 7' 7 and prevent any-tendency of lateral rockin the motor. The electric current is transmitted to the motor over theWires 11 11 and is carried to the-fields of the motor (not shown)` bythe trolley-arms 18 18 and is grounded over the track 5. The frame 19 islmount-ed upon the motor and straddles the track 5 `and is provided withthe depending hangers 20 20, to the lower ends of which the buckets 21are attached. As the said motor and its construction form no part ofthis invention, it is deemedv unnecessary to go into detail descriptionofthe same here.

Having described my invention, what .l

claim as new,land desire to secure by Letters 3. A monotrack-tramwaycomprising up.

rights having tfheirupper ends split and expanded to form sockets, andrails having-flat top surfacesand. outwardly-sloping Alianges dependingfrom said top surface, the body portions of said rails being secured inthe split portions of said uprights.

4.' In a tramway, an elevated monotrack comprising rails, bondselectrically connecting the rails together, beams supportingr the railsAand having their 4upper ends split and expanded to form sockets whichreceive said rails, and insulation interposed between the beams and therails.

5. In a tramway, an elevated monotrack comprising rails havingspaced-apart webs forming side iianges andA depending integral bodiesinterposed between said webs, bonds electrically connecting the railsvtogether, beams support-ing the rails and having ,at

their upper ends sockets which receive vthe frail-bodies, the upper endsof the beams iitting between the iianges and the body ot the rail. l ngj y6. In a tramway, an elevated monotrack flanges. .v y '9. Amonotrack-tramway comprising rails comprising rails having inclinedspacersi apart webs forming side flanges and centra depending integralbodiesinterposed between said webs, bonds electrically connect-ing therails together, beams supporting the rails and having at their upperends sockets which receive the rail-bodies, the upper ends of the beamsfit-ting between t-he flanges and the body of the rail. y

7. A monotrack-tramway comprising rails havingr spacedapart webs formingside iianges, and depending integral bodies interposed between said websand spaced from said flanges, and supports for said rails having meansfor engaging the lower edges of said flanges.

S. A'monotrack-tramway comprising rails having' spaced-apart websforming side ianges and central depending integral bodies interposedbetween said flanges, and sup ports for said rails having means forengag ing said bodies andthe lower edges 'fof said havin@ inclined sideflanges and de ,endinCr b h bodies interposed between said webs, andvsupporting-beamshaving their ends j provided with seats for said sideiianges.

'Y 10. A- monotracktramway comprising rails having"l inclined sideflanges and central depending bodies interposed between said flanges,and supportingbeams having their outer faces provided with sea-ts forsaid side anges. A

11`. A monotracl-tramway comprising -rails each having spaced-apart websforming side flanges and an integral depending body interposed. betweensaid webs,` bonds elec.- trically conneting said webs, and beams havingtheir ends` provided with sockets to receive the bodies of the rails,said sockets ybeing also provided with exterior seats for' said lianges.I

l2. A monotrack-tramway ctnnprising rails having spaced-apart websforming inclined side ,Hanges and depending bodies integral with andinterposed between said webs, bonds attached to said bodies;iish-plateslo` cated over the bonds and attached to the depending bodies, and meansfor supporting the rails, said supporting means also engaging the loweredges of said webs.

ln testimony whereof l have signed my name to this specification in thepresence et two subscribing witnesses.
